A word to express a certain state of mind. Can be used when feeling particularly down. Similar to that of 'Meh' and 'Bleh'.

Originated from a mistype from a girl on Facebook chat, when typing 'sigh' the 'u' key was pressed by mistake, it seemed fitting, and therefore 'Sugh' was created.
Used as an adjective, but also as an adverb.

Example 1:

Alice: Sugh.
Beth C: Dude same. Wassup?
Alice: Got a load going on at the moment, what with people, school yadda yadaa. You?
Beth C: Just not feeling 'it' at the moment. Sugh. :(
Alice: Sugh. :/
Beth M: I am sugh also.
Alice: Oh good, another one to join in our Sughness.
